and followed the instructions but to no solution. I even have formatted, reinstalled Mac OS X, not reinstalled VMWare and turned off IPv6, and keep having kernel panics every now and then, as often as before.
I always have them when loading a web page or doing something internet related, that's why I think the problem is with Cisco's VPN!
Are you using it?

I do have cisco vpn for school purposes and I did use it a couple of days ago. It would seem strange to me cause i already used it before on my mac. Have you deleted it already? But i'm not using cisco at the time my MacBook crashes..

Ah ok, in that case maybe it's not the same problem.
I can't delete it because I need it for connecting to the internet (Snow Leopard's own VPN won't work) and whenever I have a kernel panic I'm connected to the internet using Cisco's VPN - which is all the time I use my computer anyway...
